From November 2015 through June 2023, while associated with Titan, Ondris used an unauthorized personal email account to send and receive securities-related business communications to firm customers. Ondris did not provide copies of the emails to Titan and thereby prevented Titan from preserving the emails as required by Section 17(a) of the Securities Exchange Act of 1934 and Exchange Act Rule 17a-4(b)(4). By causing Titan to maintain incomplete books and records, Ondris violated FINRA Rules 4511 and 2010 and is suspended for one month and fined $5,000.
